Sebastian Munoz twice holed out for eagle from a combined distance of 219 yards. He also had eight birdies. Throw in a wild tee shot for double bogey, three bogeys and only five pars and it added to an 8-under 64 and a one-shot lead.
For the first time in his 1,277 rounds on the PGA Tour as a pro, Tiger Woods made bogey or worse on three par 5s in a single round. That led to a 4-over 76 — by two shots his worst score in 49 rounds at Sherwood Country Club — that left him 12 shots out of the lead and in no mood to talk.
Munoz, the Colombian who played his college golf at North Texas, finished off his bizarre round by saving par from a narrow section of the front bunker with a 15-foot putt on the 18th hole.
He was one shot ahead of Tyrrell Hatton, the hottest golfer this month, and Justin Thomas, who had a hot finish. Hatton won the European Tour flagship event at Wentworth, flew to Las Vegas for the CJ Cup and tied for third. Thomas shot 29 on the back nine at Sherwood. They each had a 65.
